Yep, that's one of the Asian hornets. Their venom dissolves flesh and signals other hornets to attack. They kill 30-40 people a year. They've accidentally been imported to France. A nest of 30 can kill a hive of 30,000 bees in a few hours. They are serious bad asses of the insect world.
God, you've just identified what I saw a few years ago here. The nastiest looking think I've seen - I had no idea their sting was so bad!
